UNIVERSAL MACHINE VISE.

invented certain new and useful Improve-- ments in Universal Machine Vises, of which the following is a specification.

Thisinvention relates to certain new and useful improvements in universal machine vises especially adapted for use on planer shaper milling machines or drill presses.

An important object of the invention is to provide a device of the above mentioned character that afl'ords proper adjustment for holding material being worked upon at any desired angle.

A further ob'ectof theinventionis to provide a vise suitable for any kind ofbench work, and one that may be employed entirely separate from the universal. features of adjustment.

A further object of the invention is to provide a vise with thoroughly practical and reliable pipe jaw attachments which can be applied very quickly and without the use of screws or bolts.

Other objects and advantages ofzthe invention will be apparent during the course of the following description.

In the drawings, wherein for the purpose of illustrationis shown the preferredembodiment of'this invention, the numera-ll designates what I will herein refer toas the base unit," it being adapted for securing to anymachine' base'plate or work bench by means ofthe slotted lugs 2 as best shown in spaced inwardly directed guide flanges 4 that are adapted forengaging longitudinally extending grooves 5 formed inthe 'slidably mounted vise jaw carriage which has termed atone end a perpendicularly extend;- ins; head portion 7 that is provided with a transversely extended threaded bore Sfor-a purpose to be described hereafter. Referring particularly to Figs. 1, 5' and 7 wherein there is shown a series of set screws 9 that adjustablv engage one of the flanges 4 and are provided for hearing against the gib key 10 for the purpose of retaining thecarriage 6 in its adiusted position. I

It is to be understood that this vise car'- riagemay' be entirely'removed from thesubbase unit 3 for the purpose of securing the same directly to a work bench orbthelike, there being provided clamping boltengaging slots 11 for this purpose. carriage 6 "is further provided with inwardly directed I flanges 12 adapted for en} gaging the outwardly projecting lugs 13 carried by the base ofthe innervise jaw 14 which is sildably associated with the said carriage; Threadedly engaging the ,bore 38 The vise jaw upwardly through the jaw base opening 21 for receiving the locking lever 22 which is retained in position by means of the adjusting nuts 23. By closely examining Figs. 8 and 9 it will be seen that the upper peripa eral edge of the opening 21 is provided with camming portions 24 that are to be engaged by the camining surfaces 25 formed upon the lower face of the lever 22 for the purpose of locking the vise jaw 18in its adjusted position. The vise jaw carriage 6 fru-th'er provided with transverse grooves or notches 26 that are adapted for receiving the drop bar 27 carried by the vise aw 18 and is adapted for use when extra heavy pieces of material are being worked upon. 7

Referring particularly to Figs. 3 to 5 inclusive and 10 there are shown vise jaw attachments adapted for converting all the said jaws so that round material may be Worked upon while in a vertical or horizontal position and whereby square stock may be held so that longitudinal edges instead of flat surfaces may be conveniently positioned for the mechanic working thereupon. In Fig. 3 there are shown pipe jaw attachments that consist of the single flange pipe engaging jaw 26 and the double flange pipe engaging jaw 27 each having a hooks'haped lug'28 formed upon its upper end and adapted for engaging a notch 29 formed in the vise jaw while a laterally extending lug 30 is formed upon the lower end of each attachment and is adapted for engaging a recess 31 formed in the main vise jaw for preventing lateral moveihent of the said attachments. It will be seen that these pipe jaws may be very readily applied and removed :t'rom the main vise jaws by first positioning the hookshaped lug '28 in the recess 29 and rocking the lower end of the said attachment towards the base of the vise jaw for positioning the lug 30 within the recess 31, and by reversing the operation the said attachments may be as readily reili'eved. In Fig. 5 there are shown apertures 32 formed in the face of the vise jaw for receiving the pins 33 formed on the attachment shown in Fig. 10, this attach ment consisting of plates 34 that are provided with intersecting substantially V- "shaped grooves 35 for the'purp'ose of adapting the vise for retaining round stock in either a vertical or horizontal position.

Referring particularly to Figs. 6 and T there is shown means for retaining the sub base unit 3 in any desired adjusted position in respect to the base unit 1, the said subbase unit 3 and base unit 1 being of substantially shell formation to provide space for this locking feature of construction. Centrally positioned within the two units and 'pivotally' secured to the base unit 1 by means of the pivot screw 36 is a hub member 3'? that is provided with an operating lever 33 which projects outwardly oi: the said unit, the said hub 37 being provided with radial lugs 39 that are adapted for pivotaiiysuu porting the locking links 40 which are ro vided at their outer ends with diagonal slots 41 for receiving the guiding and adjusting screws 42 which are secured to the base unit 1. It is the purpose of these locking links 40 to project into an annular greove 43 formed in the sub-base unit 3 for the pith pose of wedging outwardly against the wali of the sub-base unit to securely bind thereagainst for preventing relative movement between the two units, and by moving the operating lever '38 into its dotted line position as shown in Fig. 6, the locking links 40 will be withdrawn from the annular groove 43 for the purpose of allowing the sub-base unit 3 to be rotated upon the unit 1. There is further provided means for preventing the separation of the two units when the locking links 40 are not engaging the annular groove 43, this means consisting of perpendicularly extending plates 44 that are adjust-ably clamped to the base unit by means of the screws 45, there'bein'g further provided transverse ribs 46 that are adept ed -01- being positioned within the annular groove 43 formed in the 'sub base unit 40 when the clamping screws 45 are properly tightened to draw the plate 44 against the walls of the said units. Secured to the inner faces of the plates 44 are spring members 47 that are connected at their opposite ends to pins 43 carried by the floor of the base unit 1, it being seen that these spring elements will withdraw the transverse ribs 46 from the annular groove 43 when the clamping screws 45 are loosened, thereby allowing the removal of the sub b'ase unit 3 from the base unit 1 when so desired.

It is believed that the formation and relative assembly of the various elementscon stitutin'g this universal machine vise will be understood from the above detail description, thereby, requiring no furtherdescri'ption of the same. It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred T if) example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without depart ing from the spirit of the invention or the scope of the subjoined claims.
